. A'I'I'DRN EYE Patented Aug. 7, 1945 UNITED STATES PATENT OFFICE-2,381,158 VENETIAN BLIND Oscar Green, Detroit, Mich.

Application June 29, 1944, Serial No. 542,677 4 Claims. 01. 16il-l66) Mypresent invention, in its broad aspect, has

each slat so that the'slats are held in position to the end that byreversing the sides of the blind toward the source of light .twodifierent light exposures are provided, one by reversing the bottom andtop of the blind two additional exposures are provided. In looping thesupporting cords provision is made for not only securely supporting theslats but fixing their relative positions, and the entire structure issimplified, rendered more practical and efflcient, and improved overdevices in the same general category now in use.

Among the many objects and advantages of my invention are (1) to providea Venetian blind which has no fragile or complicated parts likely to getout of order; (2) to provide a Venetian blind which may be used withordinary window shades and decorations such as drapes or the like, orcurtains, and which is easily removable when not in use and may be keptclean; (3) to provide a Venetian blind whose cords may be readilyreplaced when worn or frayed by the owner without outside help, andwhich will fold up for storage, shipment, or to be taken on trips; (4)to provide a device which may be manufactured of metal, paper board,wood or the like by an ordinary stamping process and may be suitablyreinforced; and (5) to provide a blind which maybe used with anyconventionalwindow construction.

Other and equally important objects and advantages of my invention willbe apparent from the following detailed description and drawing,

' but it is" to be understood-that changes in form,

size, shape, construction and arrangement of parts may be made withoutdeparting from the spirit of my invention or the, scope of the appendedclaims.

Figure 10 is a detailed section showing the use In the drawing whereinlike characters of reference are used to designate like or similarparts:

The numeral l as used in Figures 2-3-4-5 designates the normal top of myVenetian blind structure 2. My Venetian blind is formed with slats 3which may be of metal, paperboard or the like, and may be fabricated byastamping operation. Each slat 3 has three pairs of spaced apart o ings 4along one edge. These openings are divided by a web part 5.

The supporting cords 6 of my blinds may be of any suitable type, and theoutside cords I are provided with looped eyes 8 at the top and bottomends. In hanging the blind the looped eyes 8 are simply engaged over theheads of tacks 9 or the like, so that the blinds may be quickly andeasily mounted or taken down.

In attaching the slats 3 to the cords 6, the cord is looped as at l0about the web 5. That is, a

length of cord is run through the outer opening as at a then across theunder p rt of the web as at b, then up through the inner opening as at cand across the top of the web as at d and then down through the outeropening as at e as shown in Figure 6, whereupon the loop is drawn'tightas in Figure '7 to support theslat in position on the cord. Worn orfrayed cords may be easily replaced by the owner;

A reinforcing strip ll may be mounted on a slat across the web portions.5, or metallic or plastic eyelets I2'-see Figure ill-may be used aboutthe openings 4 to reinforce the same.

From the foregoing it is believed that the operation and advantages ofmy invention will be apparent, but it is again emphasized thatinterpretation of the scope of my invention should only be conclusivewhen made in th light of the subjoined claims. a

I claim:

1. A Venetian blind comprising slats, cords supporting the slats, saidslats having pairs of openings, the cords being looped through theopenings to support the slats.

2. A Venetian blind comprising slats, and said slats being reversible inoperation, pairs 01' openings in each slat, cords supporting the slatsand looped through the openings, and said blinds being reversible as tothe side presented to the light and as to the top and bottom edges.

3. A Venetian blind comprisin spaced slats, each slat having pairs oftransversely spaced openings adjacent one edge, a cord passi throughvertically aligned pairs of openings, said cord being looped through thopenings.

4. The invention as described in claim 3 wherein the loops are formed bytraining the cord through the outside opening, then passing the sameacross the web, and through the inside opening and then across the weband through the outside opening.

OSCAR GREEN.
